How to configure log4j2 to log for HikariCP

由 半世苍凉 提交于 2019-12-11 03:33:06
问题 I have written a small Gradle project so that I can learn how to configure HikariCP and JDBC and Log4j2 all together in the same project. I have placed the below log4j2 config in the src/main/resources directory in my project. When I execute the project using gradle run I get a warning about not configuring an appender for the com.zaxxer.hikari.HikariConfig logger. Would some one kindly tell me what i am doing wrong? log4j2.xml <?xml version="1.0" encoding="utf-8"?> <Configuration status=

问题 Running this test with an invalid hostname, or user/password, it waits about 2 minutes before failing. I would ideally like to have it fail immediately if user/password is incorrect, or if the hostname/port are not correct. HikariConfig config = new HikariConfig(); config.setMaximumPoolSize(1); config.setDataSourceClassName("com.mysql.jdbc.jdbc2.optional.MysqlDataSource"); config.addDataSourceProperty("serverName", "localhost"); config.addDataSourceProperty("url", "jdbc:mysql://localhost:3306

Apparent connection leak detected with Hikari CP

问题 When using native sql operator IN i get exception. Although it throws an exception, it still works as it was intended, but the exception in the logs is a bit annoying. I think it has something to do with the IN operator. @Query("select c from Contact c where c.id in :ids") List<Contact> findByContactsIds(@Param("ids") List<Integer> contactsIds); config: spring.datasource.hikari.max-lifetime=900000 spring.datasource.hikari.leakDetectionThreshold=2000 spring.datasource.hikari.idle-timeout

Spring Boot 2.0.X 多数据源及连接池配置

由 早过忘川 提交于 2019-12-07 11:35:31
一、单数据源 我们在使用Spring Boot配置单数据源的时候很简单，只要在配置文件中加上基本的数据库连接信息和连接池配置信息就可以，通常情况下不需要指定driver-class-name，Spring Boot可以从大多数数据库的url中推断出驱动类型 # 连接配置 spring.datasource.url=jdbc:mysql://localhost:part/test?characterEncoding=utf-8 spring.datasource.username=**** spring.datasource.password=**** spring.datasource.driver-class-name=com.mysql.jdbc.Driver # 连接池配置 spring.datasource.hikari.pool-name=HikariPool spring.datasource.hikari.minimum-idle=5 spring.datasource.hikari.maximum-pool-size=10 spring.datasource.hikari.connection-timeout=30000 spring.datasource.hikari.idle-timeout=600000 spring.datasource.hikari.max
